Abstract
A microfluidic valve comprising an adhesive tape, an outlet disposed at one end of a first microfluidic channel, an inlet disposed at one end of a second microfluidic channel, wherein the inlet and the outlet are disposed in a proximity to each other, wherein the adhesive tape covers both the outlet and the inlet. A method of operating the microfluidic valve is also disclosed.
Claims7
A microfluidic valve comprising:
- an adhesive tape comprising:
- a backing layer;
- an adhesive layer;
- and
- a liner layer;
- wherein the adhesive layer is sandwiched between the backing layer and the liner layer and being joining materials by surface bonding;
- an outlet disposed at one end of a first microfluidic channel;
- an inlet disposed at one end of a second microfluidic channel,
- an wherein the inlet and the outlet are disposed in a proximity to each other,
- an wherein the adhesive tape covers both the outlet and the inlet.
7 more elements
A method comprising the steps of:
- providing an adhesive tape covering an inlet disposed at one end of a first microfluidic channel and an outlet disposed at one end of a second microfluidic channel;
- directing a fluid to the first microfluidic channel at the other end;
- building up fluidic pressure at the inlet;
- pushing a predetermined portion of the adhesive tape away from the inlet and the outlet thereby forming a pocket such that the inlet is in fluid communication with the outlet;
- and
- directing the fluid to flow from the inlet to the outlet through the pocket.
